METALY WINDOW s As-H.

Application filed February 11, 1926*.` `'Seria-1 Ivm-871705.y `v

l My invention relates to a metal window sash,` and particularly to sheet metal clamping` members.'

The object of my invention is to provide sheet `metal clamping members which may be quickly and accurately assembled in clamping. position and which are very simple in construct-ion. f

The construction and minor objects of my 1U invention will appear as the description proceeds. f

In the accompanying drawing forming a part of this specification, Fig. lis a trans verse section throughone form of sash embodyingmy invention F is a detail sectionon the lne`2-2vof` Fig. 1, and Fig. 3 is a detail showingA a diiferent form of face plate fromthat shown in Fig. 1.

In the construction shown, there is a supporting member beyond one edge of the pane of glass 11 and substantially perpendic ular to the plane. thereof. Back of' the glass, there is avriser 12 rigidly attachedv to member 10.

A rear Clamping member 13 is provided, andl isshown attached to the front face of riser 12 by meansofa nail or tack 14. Member 13 has a portion 15 at itsedge extending towards the glass. andrav flange 16 adapted-1 to rest againstthe surface of the glass. :Member 13 has aportion 17 resting against support 10, and has an offset portion 18 at the angle between' members v10y and 12. Openings 19 are provided at intervals through offset portion 18l where it joinsthel body of the member'l f A front clamping memberor face plate 20 is provided withv one edge bent to extend towards the glass at 21 and tovrform ay fla-:nge y 22 resting against the glass. -The other edge of member 20 is folded back againsty itself y on the sidetowards the pane to provide a bead 23 adapted to rest against support 10. rI'he folded portion is reverselyl bent until it forms a ilange 24 extending from the upper edge of bead 23A towards the plane of the pane. Fortion 1.7 of the rear clamping member extends between flange 24 and support 10 and against bead 23. Preferably, tongues 25 are slit at intervals in the edge of portion 17 and are bent tofrest against the side of flange 24 away from support 10, sov that the relation of the edges of rear member 13 and front member 2O is determinedby the interlocking of flange 24 between tongues25 and the edge of portion 17 andby the abutmentof `bead 23 against the edge of por'- tion 17. v f ,l

, Holes 2.6Vy are provided. atv intervals through front member 20 in such relation to holes 19 'that a screw27 may pass through each pair ofV aligning holes and into member 12. Tightening screw 27 results in clampiin the glass between flanges 16 and 22 and ho'l ing it yielding yet accurately in place.' As member 20is drawn towards the glass by screw 27, it rocks on bead 23, which in turn presses against the front edge of portion 17. Flan-ge 24 may be spaced slightly above portion `V17 ,l as shown, so that it will not interfere with the above: described rocking movement, 4while tongues; 25 hold flange 24 `in place so that bead 23 cannot slip over the edge of porti-on 17. Y

Holes- 19 and 26 furnish guides for screws 27, soy that theangle of the screws is predetermined and uniform, which aids iny hold-v ing the clamping member in place uniformly throughout its. length and` in a predetermined` manner to best perform its function. The olf-setting of portion 19 increases this guidingedect, and it' also makes provision forfportion`17 to: yieldl slightly when pressed. by bead 23., A

If desired, bead 23fmight`be omitted-- and the engagement between flan ea24, portion 17 and ,tongues 25 might be epended upon to retain the 'inner' vrand' youter member in:

pro `er relative positions, but I prefer to use bea *L 23,.asit.conceals the edge' o portion 17V iny additionL to furnishing a. reliable anclfiorafgeA for thek edge of vmember 2O. v

In Figf3 a modiiied form of outer clamp'- ing. member or face plate 20E' is shown in section, the parts corresponding. to those shown'in Fig. 1 being designated by the sameY referenceY Vcharacters with the' letter a added... It will'be noted that, while the shane of the face plate is considerably modified, it co-operates with other portions of the device in the same way asI the face plate shown in Fig. 1.

In Fig;` 3 the flange`24a is shown in contact with the subjacent portion of memberl 17?,an'd the tongue 25a is not bent up as much tongue 25'v in Fig'. 1.. It will be understood `that. the vexact elevation of flange 24. or 24a' or the: angle of tongueI 25 or 25a is a matter of detail which may be varied within considerable limits and still operate successfully.

Various changes may be made in the inner clamping member and in the means for holding the outer clamping member in place, while retaining some of the advantages of the structure of' the outer member, and variousV changes, besides those described, may be made in the outer member and inA the manner of holding it in place while retaining some ofthe advantages of the Astructure of the inner member; Obvious changes, other Vthan those mentioned above, may be made within the scope ofthe appended claims which define the invention.
